ALFRED C. STEWART, OF SANTA PAULA, CALIFORNIA.

MOTOR-VEHICLE.

SPECIFICATION forming part of Letters Patent N0. 684,322, dated October8, 1901.

Application filed July 11, 1900.

To all whom it may concern.-

Be it known that I, ALFRED C. STEWART, a citizen of the United States,residing at San ta Paula, in the county of Ventura and State ofCalifornia, have invented new and useful Improvements in Motor-Vehicles,of which the following is a specification.

The object of this invention is to provide a means of carrying the motorto free it from all vibration of the road and at the same time make itimpossible to impart any vibration to the carriage-body.

My invention employs in a motor-vehicle the combination of a resilientengine-support carried by the vehicle, an engine carried by saidengine-support and operatively connected with the driving-shaft of thevehicle to drive the same, and an alinement-maintaining connectionjournaled upon the axle and pivotally connected with the engine.

The accompanying drawings illustrate my invention.

Figure I is a fragmental view of a motorvehicle embodying my invention.Fig. II is a plan of the same, omitting the body of the vehicle, thesame being cut away on line 11 II, Fig. I. Fig. III is an elevation fromthe right of Figs. I and II. FigI IV is an elevation of ihes]pring-support viewed from the left of a indicates the wheel-carriedbody of the motor-vehicle.

1) indicates the wheel-driving axle.

'0 indicates the traction-wheel of the vehicle, which is driven by thedriving-axle b.

61 indicates a driving-wheel on the drivingaxle for rotating the same.

2 indicates a case journaled on the axle through the medium of a sleevef, through which the axle extends and in which it rotates.

9 indicates an engine operatively connect- 'ed with said driving-wheel dto rotate the same. Said engine may be connected with said wheel in anysuitable manner. For convenience of illustration I have shown itconnected by means of a sprocket wheel h, sprocket-chain i, driventhereby, and a driving sprocket-wheel which drives a shaft 70, whichdrives a pinion m, which meshes with the driving-wheel d, which is acog-wheel.

It is to be understood that any suitable Serial No. 23,244. (No model.)

means of operatively connecting the engine 9 with the driving-shaft clto drive the same may be employed without departing from the spirit ofmy invention.

n indicates a vibrating bracket or arm journaled on the driving-shaftthrough the medium of the stationary sleeve f, upon which the arm orbracket 11 is loosely mounted to vibrate.

0 indicates a resilient engine-support connected at one end with thevehicle-body a and pivotally connected at the other end with thevibrating bracket.

19 indicates the pivot for connecting the resilient enginesupport 0 withthe bracket-arm n. q indicates a pivot which supports the other end ofthe engine-support 0. Said other end, which is thus supported, iscarried by a swivel-link composed of the members '2", s, and t, whichallows a free swinging movement of the end 0' of the engine-support 0. uindicates a'compression-spring to take up the lost movement of the linkthus formed.

The resilient engine-s11 pport 0 shown in the drawings consists in aleaf-spring; but it is to be understood that the resilient enginesupportmay be variously constructed and supported without departing from thespirit of my invention, the object of this support being to resilientlyuphold the engine.

0 indicates suitable means for securing the engine to theengine-support.

2; indicates a connecting-rod journaled to the driving-axle b andpivotally connected with the engine.

w indicates the point at which the connecting-rodc is pivoted to theengine. This point is preferably located near the lower part of theengine and at a considerable distance from the driving-axle b. Theconnecting-rod Q), which is shown in the drawings, is provided with twolimbs 1 2 and a cross=bar 3, which connects them and pivots them to theengine. The limb 1 is journaled by an eye 4.- on the sleeve f, and thearm 2 is journaled to the sleeve f through the medium of the gear-casee, which contains the axle driving-wheel cl and the pinion m, whichdrives the same.

In case a sprocket-chain is used, as shown in the drawings, it isdesirable that some means be provided for adjusting the tension of thechain. For this purpose the arm 2 is adj ustably fixed by set-nuts 5 6upon the gearcase 6 at a point above the sleeve, and the arm 1 isfastened to the eye 4:, which is journaled on the sleeve. By looseningnut 6 and tightening 5 the case will be slightly rotated to tighten thechain. A reverse operation will loosen the chain.

In practical use the engine is free to move vertically by reason of theresilient support; but motion in all other directions is prevented bythe connection v, which at all times holds the engine-shaft a; parallelwith and on a plane with the driving-axle of the vehicle, at the sametime keeping the distance between said shaft and axle constant. Theenglue is thus freed from all vibration of the running-gear, but at thesame time cannot impart its own vibration to the carriage-body, as wouldbe the case it it were mounted directly thereon.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is

1 A motor-vehicle comprising a wheel-driving axle; a driving-wheel onthe drivingaxle for rotating the same; an engine operatively connectedwith said driving-wheel to rotate the same; a vibrating bracketjournaled on the driving-shaft; a resilient engine-support pivotallyconnected at one end with the vibrating bracket and at the other endwith a suitable support; means securing the engine to theengine-support; and a rigid connection journaled to the driving-shaftand pivotally connected with the engine.

2-. A motor-vehicle comprising a wheel-carried body; a wheel-drivingaxle; a drivingwheel on the driving-axle for rotating the same; anengine operatively connected with said driving-Wheel to rotate the same;a vibrating bracket-arm journaled on the driving-shaft;aresilientengine-supportconnected atone end with the vehicle-body andpivbracket; a swinging connection connecting' the other end of theresilient engine-support with the wheel-carried body; and aconnecting-rod journaled on the driving-shaft and pivotally connectedwith the engine.

4:. A motor-vehicle comprising a wheel-carried body; a wheel-drivingaxle; a driving wheel on the driving-axle for rotating the same; a caseforsaid driving-wheel journaled on the axle to allow,the same to rotatethere with; an engine operatively connected with said driving-wheel torotate the same; a vibrating bracket-arm journaled on the driving-shaft;aresilientengine-supportconnected at one end with the vehicle-body andpivotally connected at the other end with the vibrating bracket; meanssecuring the engine to the engine-support; and a connecting-rodadjustably connected with said case and pivotally connected with theengine, substantially as set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, at Los Angeles, California, this5th day of June, 1900. V

ALFRED C. STEWART.
